本文使用docker-compose运行wordpress，使用已有的mysql数据库，外部的nginx开启https反向代理到wordpress。如果你的域名还没有备案请先去备案。

编写启动文件

编写wordpress.yml，然后执行 docker-compose -f wordpress.yml up -d 启动容器

172.18.0.1:3308是我自己的mysql地址

version: "3"
services:
  wordpress:
     image: wordpress:latest
     ports:
       - "8000:80"
     restart: always
     volumes:
      - /opt/wordpress:/var/www/html
     environment:
       - WORDPRESS_DB_HOST=172.18.0.1:3308
       - WORDPRESS_DB_USER=wordpress
       - WORDPRESS_DB_PASSWORD=wordpress

如果你之前没有现成的mysql数据库，可以按照官网的教程编写配置文件

version: '3.1'
services:
  wordpress:
    image: wordpress
    restart: always
    ports:
      - 8080:80
    environment:
      WORDPRESS_DB_HOST: db
      WORDPRESS_DB_USER: wordpress
      WORDPRESS_DB_PASSWORD: wordpress
      WORDPRESS_DB_NAME: wordpress
    volumes:
      - /opt/wordpress:/var/www/html
  db:
    image: mysql:5.7
    restart: always
    environment:
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wordpress
      MYSQL_PASSWORD: wordpress
      MYSQL_RANDOM_ROOT_PASSWORD: '1'
    volumes:
      - /opt/mysql:/var/lib/mysql

这里需要去wordpress后台配置地址，修改为我们最后带域名的地址。
访问 ip:8000/wp-admin

配置Nginx

这里使用nginx开启https并反向代理到worpress,如果没有安装nginx，请先安装nginx。HTTPS证书可以去阿里云申请免费的SSL证书，这里的坑比较多，请注意仔细看配置文件。
我们的案例域名是aispider.cc,我们把域名全部重定向到 https://www.aispider.cc
vi /etc/nginx/nginx.conf

server { 
        listen  80;
        server_name     aispider.cc;
        location / { 
           if ($host !~* ^www) { 
                set $name_www www.$host;
                rewrite ^(.*) https://$name_www$1 permanent;
           }
           rewrite ^(.*) https://$host$1 permanent;
        }
    }
    server { 
        listen  80;
        server_name  www.aispider.cc;
        rewrite ^(.*) https://$host$1 permanent;
    }
    server { 
        listen       443 ssl http2 default_server;
        server_name  www.aispider.cc;
        ssl_certificate "/opt/cer/aispider.cc.pem";
        ssl_certificate_key "/opt/cer/aispider.cc.key";
        ssl_session_cache shared:SSL:1m;
        ssl_session_timeout  10m;
        ssl_ciphers PROFILE=SYSTEM;
        ssl_prefer_server_ciphers on;
        location / { 
           if ($host !~* ^www) { 
              set $name_www www.$host;
              rewrite ^(.*) https://$name_www$1 permanent;
           }
           proxy_pass  http://localhost:8000;
           proxy_redirect     off;
           proxy_set_header   Host $host;
           proxy_set_header   X-Real-IP $remote_addr;
           proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header   X-Forwarded-Host $server_name;
           proxy_set_header   X-Forwarded-Proto https;
           proxy_set_header   Upgrade $http_upgrade;
           proxy_set_header   Connection "upgrade";
           proxy_read_timeout 86400;
        }
    }

修改wordpress配置文件

如果直接代理过去，会有很多问题，比如循环重定向转发，js、css等资源走的是http请求，地址重定向为localhost，我也是踩了很多坑才配置好。

修改/opt/wordpress/wp-config.php，这个是docker容器挂载的卷，增加如下内容
vi /opt/wordpress/wp-config.php

define('FORCE_SSL_ADMIN', true);
if (strpos($_SERVER['HTTP_X_FORWARDED_PROTO'], 'https') !== false){ 
    $_SERVER['HTTPS'] = 'on';
    $_SERVER['SERVER_PORT'] = 443;
}
if (isset($_SERVER['HTTP_X_FORWARDED_HOST'])) { 
    $_SERVER['HTTP_HOST'] = $_SERVER['HTTP_X_FORWARDED_HOST'];
}
define('WP_HOME','https://www.aispider.cc/');
define('WP_SITEURL','https://www.aispider.cc/');
